1 Claim. (CI. 57-10) This invention relates to a spring winding deviceior tow cables.

An object of the invention is to eliminate the chafing of a tow rope orwire, which rides over a roller on the bulwark of a ships stern bycovering the tow rope or wire at the portion subject to such wear with aheavy steel coiled wire spring.

The spring will act as a protector to the tow rope or wire and at thesame time will allow the towing wire to bend in any direction.

If the wire spring should wear out, it can be easily and quickly removedand a new one installed by the use of the present device.

With the above and other objects and advantages in view as will appearas the nature of the invention is better understood, the same consistsin the novel construction, combination and arrangement of partshereinafter more fully described, illustrated in the accompanyingdrawing and pointed out in the appended claim.

In the drawing forming a part of this specification and in which likecharacters refer to like parts throughout the several views:

Figure 1 is a top plan view of a tow rope connected to the stern of aship.

Figure 2 is a rear view of an embodiment of the invention in operativeposition, and

Figure 3 is a sectional view on the line 3-3 of Figure 2.

Rererring more in detail to the drawing, the numeral It indicates thestern of a ship, having a bulwark l2 on which is mounted horizontal towrope guide rollers It, on the deck 18 are also positioned vertical guiderollers 20.

A tow rope or wire 22 passes through the aforesaid rollers over the deckl8 and to a towing reel not shown.

The spring winding device comprises a handle 24 having a semi-circularhooked end 26.

The handle 24 is provided with an elongated vertical slot 28 which isadapted to receive bolts 30 which are positioned in openings in theclamp 32.

The clamp 32 has a straight short portion 34 and a semi-circular curvedportion 36 which is curved reversely to the hooked end 26 of the handle24.

The tow rope or wire 22 is adapted to be placed between the hooked end26 of the handle 24 and the curved portion 36 of the clamp 32 and whenthe nuts 38 on the bolts 30 are tightened, the tow rope or wire isrotatably retained therein.

The handle 24 at its extreme lowermost point is provided with anapertured car 40 through which the spring 42 is guided and wrappedaround the tow rope or wire 22.

The method of winding a coiled spring on the tow rope or wire is asfollows:

A cable clamp 44 is positioned on the tow rope or wire 22 .toward thetowing reel and secured in position by means of a set screw 46.

One end of the spring 42 is drawn through the apertured ear 40 andsecured to the tow rope or wire 22 by the cable clamp 44.

The clamp 32 and handle 24 are placed on the tow rope or wire 22 and theclamp 32 is adjusted and set to a loose fit around the tow rope or wire22.

The handle 24 is then turned around the tow rope or wire in thedirection that the spring 42 is wound until the spring 42 is completelyplaced on the tow rope or wire 22.

The handle 24 and clamp 32 can then be removed or remain on the tow ropeor'wire 22 as desired.

The spring 42 can be removed from the tow rope or wire 22 in the samemanner except that the removal is started at the after end of thespring.

It is obvious that numerous changes might be made in the details of theconstruction and arrangement of parts of the device and it is desired tocover the present application and any patent resulting therefrom themodifications in structure, material or employment of mechanicalequivalents which may be within the spirit of the invention and thescope of the appended claim.

Having thus described the invention, what is claimed as new and desiredto be secured by Let- REFERENCES CITED The following references are ofrecord in the file of this patent:
